Description
Technical Field
The utility model relates to the technical field of cab collision safety, in particular to a disconnected energy-absorbing cab front suspension bracket.
Background
The front suspension of the current light truck cab generally adopts a front overturning structure form that an annular damping rubber bushing is used for damping, and damping rubber is embedded and installed in a front suspension support. Because the front suspension bracket is usually a steel casting and the rubber bushing has higher rigidity, the front suspension is integrally more rigid, when frontal collision occurs, the front suspension bracket and a frame connecting bolt can be sheared and failed, and the frame is bent and torn seriously, so that the deformation of a cab is increased, even the cab is separated from the frame and overturned, the collision energy cannot be well dispersed and absorbed, and the safety of passengers is reduced. Meanwhile, after collision, the frame is seriously bent and broken, and the overall maintenance and replacement cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a disconnected energy-absorbing cab front suspension bracket aiming at the defects of the prior art, and solves the problems that the conventional front suspension bracket is usually a steel casting, the rigidity of a rubber bushing is higher, the front suspension is integrally rigid, the front suspension bracket and a frame connecting bolt are likely to be sheared and fail when frontal collision occurs, the frame is bent and torn seriously, the deformation of a cab is increased, even the cab is separated from the frame and overturned, the impact energy cannot be well dispersed and absorbed, and the safety of passengers is reduced.
The utility model is realized by adopting the following technical scheme:
a disconnected energy-absorbing cab front suspension bracket comprises a front suspension bracket main body, an energy-absorbing connecting plate and a pin shaft; the energy-absorbing connecting plate is of a C-shaped structure with a curled steel plate, a rolling lug is arranged at the upper end of the energy-absorbing connecting plate and is hinged with the front suspension support main body, and the lower end of the energy-absorbing connecting plate is provided with a straight section hole and is fixed on the frame through a bolt.
Preferably: the pin shaft is of a detachable structure with two limit ends.
Preferably: the front suspension bracket main body is made of cast aluminum alloy.
Compared with the prior art, the utility model has the following beneficial technical effects:
the utility model utilizes the fracture of the front suspension bracket of the cab and the tensile deformation of the energy-absorbing connecting plate during the front collision to quickly absorb part of the impact energy, guides the cab to move backwards, reduces the deformation of the cab and ensures the living space of passengers.

1. A front suspension mount body; 2. an energy-absorbing connecting plate; 3. and (7) a pin shaft.
Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a detailed description of the present invention will be given below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict. In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.
The first embodiment is as follows:
as shown in fig. 1, a disconnected energy-absorbing cab front suspension bracket comprises a front suspension bracket main body 1, an energy-absorbing connecting plate 2 and a pin shaft 3; the energy-absorbing connecting plate 2 is of a steel plate curling C-shaped structure, the upper end of the energy-absorbing connecting plate is provided with a rolling lug and is hinged with the front suspension bracket main body 1 through a pin shaft 3, and the lower end of the energy-absorbing connecting plate is a straight section opening and is fixed on the frame through a bolt with the front suspension bracket main body 1; the pin shaft 3 is a detachable structure with two limit ends; the front suspension bracket main body 1 is made of cast aluminum alloy.
When a serious frontal collision occurs, under the action of an impact force, the front wall of a cab deforms and the whole vehicle body retreats, the lower end of the front suspension bracket main body 1 is fixed with the vehicle frame, the upper end of the front suspension bracket main body is subjected to a larger bending moment and is torn from a crack guide hole under the action of a backward longitudinal force, meanwhile, the C-shaped energy-absorbing connecting plate 2 has certain C-shaped deformation, the two jointly act to effectively buffer and absorb the larger impact energy at the initial stage of the collision, primary energy absorption is realized, the impact force transmitted to the vehicle body and the vehicle frame is greatly reduced, and the phenomenon that the connecting bolt is cut off or the vehicle frame is bent and broken is prevented. After the front suspension bracket is completely disconnected, the cab continues to move backwards under the action of inertia and residual impact energy, the C-shaped energy-absorbing connecting plate 2 continues to be stretched and deformed to absorb the residual impact energy and guide the cab to retreat to convert part of the impact energy into kinetic energy of the cab until the impact force disappears, secondary energy absorption is realized, the C-shaped energy-absorbing connecting plate 2 can still ensure that the upper end of the C-shaped energy-absorbing connecting plate is connected with the upper part of the fracture bracket, and the lower end of the C-shaped energy-absorbing connecting plate is connected with the frame, so that the cab is effectively connected with the chassis frame. The impact force received by the cab in the whole impact process is low, the deformation of the cab is reduced to the maximum extent, the impact force action time is prolonged, and the condition that the driver and passengers have enough living space and the received acceleration is minimum is ensured.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
